GDL1850 is a graphitized carbon plate, commonly used as a gas diffusion layer and electrode for fuel cells. Its through plane resistance is less than 13.3 mΩcm2. The thickness is 1.85mm and is measured at 50 kpa.
GDL1850 has a density of ±0.85 g/cm3 and a through plane resistivity of 70mΩ-cm instead of 100mΩ-cm from the classic Spectracarb grades. Voltage loss is 25mV. This product is a close alternative to Spectracarb 2050A-7590.
